What I meant was that Avast!, NOD32 and AVG have far fewer complaints than the others that I mentioned. True all 3 have paid versions but my post was not
targeted at them rather it was targeted at Kaspersky, Symatic and McAfee.
Maybe I should have phrased my post differently. My bad.
After using avast for a while I switched to the paid version (needed command line feature) and don't regret it one bit.
